Battery springs, also known as contact springs, are used with batteries to maintain a consistent electrical connection between the battery’s terminals and the device it powers. Battery springs are typically made of metal, such as steel, copper or brass, and are designed to exert a consistent force on the battery’s terminals to ensure good electrical contact.
When a device is connected to a battery, the battery springs compress slightly, bringing the terminals into contact with the device’s electrical contacts. This allows electrical current to flow from the battery to the device, powering it. As the battery discharges, the springs may relax slightly, maintaining good contact between the terminals and the device’s contacts.
Battery springs are often found in devices that require a replaceable battery, such as flashlights, remote controls, and other small electronics. They are typically located inside the battery compartment and can be replaced if they wear out or become damaged.
It’s important to note that there are various types of battery springs with different geometries and materials, each having specific characteristics that make them suitable for different types of batteries and devices.
